Dear Aspirants ,

I hope you are doing well !

Im really happy to say that if you are going through reality part then every chapter is important because if you didnt go through individually or separately then you will not able to know the importance of chapter but if you are going through any web series then you must be complete all season of series because every season is interlink to each other and it will have lots of thriller and suspense's so in that way we can go through biology it is also same so for bright future you must go through every part of chapter but if you wants to only scores in exam then you can go through previous 5-6 years questions papers and you will get approximate 40-50% marks of questions in exam .

I hope it will helpful

Thanks
